IMPROVEMENT IN MACHINES FOR SOW ING SEED BROADCAST.

Specification forming part of Letters Patent No. 17,429, dated June 2, 1857.

2 is atransverse section on w as. Fig. 3 is a transverse section on y y. Fig. 4 is a longitudinal section on a z, taken through line at m of Fig. 2. Fig. 5 is a transverse section of discharge-regulator and reciprocating scatterer, showing position of stirring-pin projecting upward from the scatterer.

Similar characters of reference denote the same part.

The object of my invention is the graduatin g of the seed-discharge, effecting the agitation of the seed, and scattering the same after passing from the hopper.

The invention consists of a deep graduatingpiece capable of vertical adjustment in a slot through the bottom of the hopper, this piece having alternate recesses cut from the upper edge of one side to the under edge of the opposite, so as to give larger openings as the piece descends through the slot, and having attached to its bottom so as to reciprocate in contact with the same an inclined scatterer, with pins passing upward through therecesses of the said piece, the construction and operation of the aforesaid combination being as follows:

In the drawings, H is the hopper, having a slot passing longitudinally through its bottom in which is the deep graduating-piece Gr, held in any desired position by the pins or on the ends of the hopper, and the holes b in the slidepieces a, secured to the ends of the aforesaid graduating-piece G. This piece has the inclined recesses d arranged alternately,- as shown in Fig. 1.

To the bottom of the graduating-piece G is attached the scatterer S by screws 0, passing through slotsfof the scatterer, so as to admit of the reciprocation of the scatterer a distance equal to the length of the slots. This reciprocation is effected by a lever, L, attached to the scatterer by a screw, g, and provided with a slot, which receives the pin it, connected with the hopper. From the scatterer arise pins '5, running in the recesses 01 of the piece G.

In operation the position of the graduatingpiece G will determine the size of opening for the seed, and thus regulate the discharge. The reciprocation of the scatterer by the hand of the operator applied to lever L moves the pins 2' within the recesses d and prevents the packing of the seed. After the passage of the seed from the hopper it falls upon the inclined moving surfacesnn, and is thusinsured a suitable distribution over the surface of the ground. The raising of the piece G until the scatterer comes in contact with the bottom of the hopper efiectually closes the dischargeopenings and prevents further discharge.

1 am aware that vibrating scatterers with upward-projecting pins have been used in connection with the bottom of the hopper, but incapable of vertical movement. I am also aware of the use of notched bars for graduating the seed-discharge. Therefore I do not wish to be understood as laying claim to these devices of themselves; but

What I do claim is- I The vertically-adjustable graduating-bar G with recesses, as described, in combination with the vibrating scatterer and agitator connected therewith, when said parts operate together as set forth.

In testimony whereofI have hereunto signed my name before two subscribing witnesses.
